The two Gemini substations "Buitengaats" and "ZeeEnergie" have left the Hoboken yard, near Antwerp, to begin their journey towards the Gemini offshore wind farm, located 85 km north of the island Schiermonnikoog in the Dutch North Sea.

In August 2013 Smulders Projects, subsidiary of Smulders Group, and Sif Group received an order from Van Oord Offshore Wind Projects b.v. for the production of 150 Transition Pieces for the Gemini Windfarm.
